France has suggested it will extend its military operation against jihadists to Libya, where extremists increasingly have a strong hold, reports The Telegraph.
French Prime Minister Manuel Valls called on Friday for international efforts to crush the Islamic State jihadist group (Isil) to extend to Libya.
"We are at war, we have an enemy, Daesh [Islamic State group], that we must fight and crush in Syria, in Iraq and soon in Libya too," Valls said, using an Arabic acronym for the group.
Speaking four weeks after IS gunmen and suicide bombers attacked Paris, Valls told France Inter radio the threat of further outrages remained "because we have hundreds, even thousands of young people who have succumbed to radicalisation".
French planes carried out surveillance flights over Libya last week.
Libya has slipped into chaos since the fall of Muammar Gaddafi in 2011 which Isil has exploited. The UN believes 2,000 to 3,000 fighters are operating there, including 1,500 in the coastal city of Sirte.
Tunisia reopened its border with Libya on Friday, 15 days after it shut the frontier following a suicide bombing in Tunis claimed by IS, the interior ministry said.
The attack, which killed 12 people, prompted Tunisian authorities to ramp up surveillance and security at its borders and reimpose a month-long state of emergency as they try to grapple with the increased threat emanating from lawless Libya.
